I will assume that you are asking about Syme's statement in chapter 5 of the novel that "the whole notion of goodness and badness will be covered by only six words" (51). What those six words may be is a matter of speculation, because Syme never comes out and states them. However, I think the more important notion here is the elimination of language and the degradation of language to is basest form in order to stifle creativity and free thinking. Syme later in the chapter states that, "The whole climate of thought will be different. In fact, there will be no thought, as we understand it now. Orthodoxy means not thinking—not needing to think. Orthodoxy is unconsciousness” (53). The “orthodoxy” that he is referring to is a complete submission to big brother. In order to completely submit, one must not question the authority pressed upon them. They must blindly believe anything that they are told and blindly do anything that they are told to do. The Goal is to make everyone the exact same and to stifle any creative thought through the destruction of language. Later in the novel Winston states that, “In the end the party would announce that two and two made five, and you would have to believe it” (80). This means that, against your own knowledge and common sense, you must “swallow” anything that Big Brother tells you. Newspeak is a way of “dummying down” the people by limiting their ability to be creative.
If I were to speculate the six words, I would say that they would be something like:
